Baseus UnionJoy 17-in-1

Use the USB mix to organize the desk

The documented layout provides three USB-A 3.0 connections and two USB-C 3.0 connections, alongside two USB-A 2.0 sockets. Put low-bandwidth input devices on the slower pair so the faster connections remain available. Ethernet and card readers cover other common reasons for keeping extra adapters on a desk.

Its included supply does not charge the laptop

The listing specifically says the included 36W adapter powers the dock itself. Laptop charging needs an additional charger and cable connected to the PD input. This matters when comparing an apparently complete desktop package with another dock that already includes host charging power. We have not established net laptop wattage after pass-through overhead.

Make three screens a documented configuration

The two HDMI outputs and DisplayPort output support the product’s advertised three-monitor role, but a port count alone does not settle operating-system behavior or simultaneous refresh rates. Keep those details unconfirmed until the precise laptop and screen combination is covered. A detachable stand allows a different placement choice; measure cable reach in that orientation rather than assuming the same layout works everywhere. UnionJoy is a connectivity option, not evidence that every attached display will run at its own maximum mode.
